At least 67 sailors were killed and 60 others were injured in a suicide blast triggered by Tamil Tiger rebels in central Sri Lanka on Monday, the military said. "They have so far recovered 67 bodies and there may be more," military spokesman Brig. Prasad Samarasinghe said about the explosion that occurred close to the town of Dambulla. He said the rebels rammed a small truck loaded with explosives into a naval convoy. "All these people were without weapons and were going on leave," Samarasinghe said.
